The Watcher of Stormhaven: the Sacred Rune (Vol. 96)

Summary

In a forgotten archive deep beneath the city library, a silent archivist who can hear the whispers of old books discovers a velvet black thread that absorbs all light around it that could awaken a dormant magic capable of vaporizing entire cities. Pursued by a silent, phantom entity that stalks the coastal fog, they must race against time before the iron gates of the underworld swing open.
